Guys it's pretty fast to just test it. If you won't, I will when I get home.
Some fan designs work better this way.

It works, i am seeing about 5 degree drop in temperature.

Those readings are working against physics and definitely not accurate.

Not necessarily. The difference between the efficacy of push or pull would be determined by the design and layout of chips/hot spots as well, not simply direction.

I have a Z9 mini myself and seen the inside, there is no way for an exhaust fan to be more efficient than an intake fan, placed either side of the Z9 mini.
Pulling air out of Z9 mini is like placing a dense fabric air filter in front of the intake, restricting the airflow and reducing the efficiency.

Whats the difference between pushing and pulling air through the same space?

The fan on Z9 mini is both High static pressure and High CFM.

In push configuration the fan pulls in air from the open with nothing resisting and allows more air to push the heat away from the heatsinks.
When you set the fan to pull air out of the Z9 mini, the components inside cause blockage which slows the fan down.

Pull or Push configuration on High static pressure and high CFM fans should produce similar results.

thank you for your reply. Like i said, i'm no expert but i am seeing lower temps and slower fan speed so its quieter and cooler now.
